7 Claims.

This invention relates to improvements for shuttle boxes for looms andit is the general object of the invention to provide a box built up ofindividual units each of which is complete in itself.

It has been common practice heretofore in the manufacture of fancy loomsto cast all the cells of the gang of shifting shuttle boxes in onepiece. As a result of this construction it has been difin ficult topolish the doors and backs of the shuttle boxes without the expenditureof considerable effort. It is an important object of my presentinvention to provide a built up gang of boxes each cell of which is madeof separate pressed steel 15 parts and to bolt the several partstogether to form the gang.

Single shuttle boxes have heretofore been lined with a wear resistingsmooth material, such as sheet Bakelite or the like, but it has beenvery 9 difficult to use this material in prior multi-cell boxes becauseof the problem of securing the sheet material to the cells. It isanother object of my invention to provide sheets or plates of a smoothwear resisting material such as Bakelite :5 to be incorporated into theconstruction of the assembled boxes and held in place by the tie boltsor the like which hold the several cells together.

It is a further object of my present invention to form the guide tonguesfor the gang on blocks which space the tops and bottoms of the cells andthese blocks are preferably made of an improved wearing material, suchas Bakelite. The tops and bottoms of the cells are formed with 13.?small tongue projections which engage and reinforce the tongues on theblocks.

Where guide tongues of a length greater than the height of the cells isdesired it is a further object of my invention to mount additionalblocks 40 similar to those between the cell forming plates above andbelow the cells.

It is a further object of my invention to provide an improved guard forthe free ends of the binders, the guard serving to tie the several unitsor 15 cells together and being held in position by the same means whichholds together the several units.

With these and other objects in view which will appear as thedescription proceeds, my insso vention resides in the combination andarrangement of parts hereinafter described and set forth hereinafter.

In the accompanying drawings, wherein a convenient embodiment of myinvention is set forth,

Referring to the drawings, the lay I0 is shown as provided with innerand outer guides H and i2, respectively, which are grooved in the usualmanner as at l3 for the purpose of guiding the boxes as they are shiftedto difierent vertical positions by means of a box lifter rod l4.

As already stated the gang G of shuttle boxes is made up of a pluralityof cells each complete in itself and each similar to the other cells. Ihave shown my invention applied to a two cell gang having upper andlower boxes 13 and B, but it is to be understood that the invention canbe extended to provide a box having any desired number of cells. Sincethe boxes B and B are alike a description of one of them, namely theupper box, will sumce for both.

In forming the box I provide a top member or plate 20 made of flat sheetmetal, such as steel, and provide the inner end thereof with an enlargedhead 2| having front and back bolt holes 22 and 23, respectively. Asmall tongue 24, shown in Fig. 5, projects inwardly from the rear partof the head 2] to extend into the groove 13 of the guide II. Theintermediate part 25 of the plate 20 is of reduced width while the outeror left end as viewed in Fig. 5 is enlarged as at 26 and provided withbolt holes 27. A binder pin hole 28 is also provided which is preferablyforward of the holes 2i, and as is the case at the opposite end of theplate the outer or left end is provided with a tongue 29 to enter thegroove l3 of the outer or left guide I2.

The head 2| extends rearwardly as at 30 beyond the rear edge 31 of theplate which extends from the extension 30 to the opposite end of theplate.

As shown in Fig. 3 for instance the rear edge of the plate is bentdownwardly to form an upper back wall 32 for the top rear edge of theshuttle. This wall 32 may be struck from an original plate having awidth represented by the full transverse dimension of the head 2!, thisconstruction permitting the extension 30 and the wall 32 to be formedwithout wasting material. The bolt holes 23 are in the extension 33 soas to lie behind the front surface 33 of the wall 32, see Fig. 3.

The lower plate 35 as shown in Fig. 5 is similar to the upper plate butof the opposite hand and has an upstanding bottom rear wall 36 similarto and in alignment with wall 33 and has also a rear extension 31 withrear bolt holes 38 similar to the parts 23 and 39 of the upper plate.The lower plate also has a tongue 39 similar to the tongue 24. Theextension 3'! is a part of a head 40 similar to head 2i and has frontbolt holes II similar to holes 22. At the other end of the lower plate35 there is a second head 45 having bolt holes 46 and a tongue 47 andalso a binder pin hole 48 corresponding to the hole 28.

The tops and bottoms of the cells may be made of appropriate materialsuch as sheet steel and are the same with the exception that they are ofopposite hands, the shuttle engaging walls 32 and 36 extending towardeach other.

For each cell I provide three blocks 5%, 5i and 52, respectively, whichas shown in Fig. 5 are formed preferably of a composition material, suchas Bakelite. The block 5! has bolt holes 55 to register with the holes2! and and also has a tongue 56 to be located between the top and bottomtongues 29 and 47. The inner end of the block 5!) may be rounded as atEl to avoid possible injury to the shuttle and the block is alsoprovided with a tapped hole 58 to receive a screw 59 which holds binderspring 63 in place. The tops and bottoms of the block 553 are flat andparallel and the height of this block, as well as the height of theother blocks, determines the vertical dimension of the cell which inturn is regulated by the height of the shuttle. The plates 25] and 35are so constructed, and the rear walls 32 and 36 are of such height asto permit the use of a variety of heights of blocks so that the top andbottom plates may be used to accommodate shuttles of differing heights.

Block 5| has a pair of bolt holes Iii which register with upper andlower holes 22 and M, respectively, and the inner rear edge of thisblock may be rounded as at 62 to facilitate entry of the shuttle intothe box. The rear surface 63 of block 5| may be parallel to the back ofthe box and assist in defining the mouth of the cell.

In certain looms it is desirable to have a shuttle box with a so-calledwide mouth to facilitate thread control, while in other looms theordinary mouth which is only slightly wider than the shuttle issatisfactory. In order to meet both of these conditions I provide twotypes of blocks 5!, that shown in Fig. 1 being for the narrow mouth, andthat set forth in Fig. 9 being used to form a wide mouth. When a widemouth is desired the block is narrower, as indicated in Fig. 9 at 5, anda rear surface 66 lies farther forward with respect to the box back thandoes surface 63 of block 5!. By the provision of these two types ofblocks I am able to construct a shuttle box which may have either thewide or the usual mouth.

The third block 52 may have a flat front face 10 and is provided withtwo bolt holes l2 which register with top and bottom bolt holes 23 and38 and this block also has a guide tongue l3 lying between the tongues24 and 39. The front surface It is preferably in alignment with theinner surfaces of the walls 32 and 36, as suggested in Fig. 3 so as toprovide a smooth surface for the back of the shuttle as the latterenters the box.

When assembling the two units shown in Fig. 2 the blocks are insertedbetween the plates as suggested in Fig. 5 and then the plates aligned,after which bolts for the outer end of the gang are passed through theholes 2?, 55 and 36 of each cell and clamped tightly by nuts 8 I. In asimilar manner bolts 83 are passed through the aligned holes 23, I2 and38 of each cell and held in place by nuts 84. The clamping of top andbottom plates of these cells against the blocks holds the latter rigidlyin place and enables them to space the plates 2!] and 35 the properamount for the shuttle to be used. The bolts also hold the tongues 24and 39 at the inner end of the box tightly against the top and bottomrespectively of the tongue I3 to prevent undue wear of the latter as theboxes rise and fall. This same condition exists also at the other end ofthe box with respect to tongue 56.

In order that the box structure may be complete I have set forth binders92 which, however, form no part of my invention nor is my presentinvention concerned with the method of mounting them, which includes abinder pin Hi to pass through the aligned holes 28 and -28 and alsothrough cylinders Q2 which may afford an eccentric mounting for acasting Q3 secured to the binder 96. As shown herein each binder has aninwardly projecting tongue 95 to limit outward motion of the binder whenstruck by the incoming shuttle.

A guard Iflfi for these tongues 35, however, is a part of my presentinvention and includes a single piece of metal which is common to allthe cells, having horizontal top Id! and bottom I62 wings respectivelywhich are clamped against the top plate 29 of the upper cell and lowerplate 35 of the bottom cell, respectively, by bolts I03 which passthrough holes 22, BI! and GI. In this way the last named bolts hold theguard, the forward end of the heads 2i and MI, and the blocks 5! tightlyin place. The guard may include a vertical web IE6 and arms I9? and IE8struck parallel to the floors of the boxes. The upper arm I0? and thetop wing IIBI confine the tongue 95 of the upper box, while the lowertongues lies between the arms IIl'l and IE8.

A bracket III} may be secured in any approved manner as by rivets I I Ito the bottom cell to provide connection with the box lifter rod I4, andit is to be understood. that the latter derives its reciprocatingmovement from any approved form of box motion.

The structure and method of assembly already set forth provides a gangof boxes the floors of which are metallic, but it may be desired to usea non-metallic floor. in which case I provide a floor plate I28 made ofcomposition material, such as Bakelite, having inner and outer tonguesI2! and I22 to align with tongues 39 and M, respectively. This plate mayhave rear inner bolt holes I23 for the bolts 33, forward inner boltholes I24 for the bolts I63, and outer bolt holes 625 for the bolts 88.Each of the plates I26 may also be provided with a perforation I26 forthe binder pin 9i. When used the plate I29 will be located below theblocks 50, 5! and 52 of the associated cell and will be held in place bythese blocks and the pressure of the tie bolts. Plates I20 lie flatalong the bottom plate 35 of each cell and serve to provide an improvedfloor for the shuttle entering the cell.

Should it be desired to provide the gang of boxes with additional guidetongue areas, a block I33 similar to block 52 may be placed above thetop plate 2%) of the gang and held in place by bolts I3I which press ona wear plate I32, and in similar manner a second lower block I33 alsolike block 52 may be held by the bolts I3I pressing on a wear plate I34,as shown in Fig. 6.

From the foregoing it will be seen that I have provided a gang ofshuttle boxes built up of individual cells each complete in itself, thetops and bottoms of each cell being formed of two plates which aresimilar to each other but of opposite hand. It will also be seen thatthe extension 30 provides material for the bolt holes 23 withoutrequiring a waste of material, since the top rear wall 32 is struck downfrom a sheet the original width of which corresponds to the width of thehead M. It will also be seen. that the metallic tongues, such forinstance as 24 and 39 reinforce the tongue 73 of the blocks 52. Theheight of the blocks is determined by and may be varied in accordancewith the height of the shuttle to enter the box. It will further be seenthat the forward inner block may be of the form shown either at El or 65depending upon the width of the box mouth. The box floor I 20 formed ofa smooth wear resisting non-metallic material such as bakelite, is heldin place by the blocks and the bolts passing therethrough.
